Definitions
- the invention relates to a setting method for anchoring a fastening element with an outer diameter and with a mixing section in a substrate by means of a curable, multicomponent mass.
- a hole is created, this cleaned and with a curable, multi-component mass, eg. B. a two-component mortar mass filled.
- a curable, multi-component mass eg. B. a two-component mortar mass filled.
- the fastener is placed in the filled wellbore. After curing of the mass, the fastener has high load values.
- Such fasteners are anchored to mechanically anchored fasteners without spreading forces in the ground, so that small edge and center distances of the anchored fasteners in the ground are possible.
- At the free end of anchored in the ground fastener attachments are set, for example, nuts on the ground.
- the object of the invention is to provide a setting method for anchoring a fastening element in a substrate by means of a curable, multicomponent mass that requires no prior cleaning of the borehole.
- a receiving space in a non-load-influencing area in the ground for receiving a portion of the remaining drill hole in the hole or cuttings is created at the bottom of the hole.
- 5% by weight to 25% by weight based on the total mass of the material to be removed from the borehole, remains in the borehole.
- the drill can be pulled during the drilling process out of the wellbore and then reintroduced into the borehole until reaching the borehole depth to be created, wherein z. B.
- An uncleaned wellbore is understood to mean a wellbore from which no drilling debris or cuttings have been removed by means of separate devices such as brushes or blow-out devices.
- the amount of curable composition to be introduced depends on the volume remaining between the borehole and the fastener. For example, the borehole is filled in half or two-thirds with the hardenable, multi-component mass. Any excess amount of the curable composition exits from the borehole when the fastener is set.
- the mechanical screwing in of the mixing section provided with the fastening element which, for example, directly in a tool holder of the rotary drive device, such.
- the components of the introduced hardenable mass are mixed and at the same time a part of the drill hole located in the borehole or cuttings are mixed into the hardenable mass.
- the rotary drive device is decoupled from the fastener. After expiration of the temperature-dependent curing time of the hardenable mass an attachment can be fastened to the free, protruding from the ground end of the fastener.
- the setting method according to the invention is distinguished by the faster course and a significantly lower dust load. Furthermore, fewer tools or tools for creating the anchorages are required because the well cleaning can be dispensed prior to the introduction of the curable, multi-component mass.
- the nominal diameter of the 1.05 to 1.5 times the outer diameter of the fastener corresponds, so that a sufficient annular gap between the borehole and the fastener for the displaced during insertion of the fastener amount of curable, multi-component mass is ensured, bringing a complete Enclosing the set fastener over the entire required anchoring length is ensured.
- the created hole depth is a maximum of 15% greater than the required anchoring length of the fastener, whereby a sufficiently large receiving space at the bottom of the hole for the remaining drill hole or cuttings present, but the cost of creating the borehole is not excessive in hard surfaces.
- the components of the curable, multicomponent mass are introduced unmixed into the wellbore, which can be dispensed with a downhole mixing device on the extrusion device.
- An injection tube for supplying the components from the Auspress réelle in the borehole is thus sufficient.
- the components are inserted axially parallel to one another, in a side-by-side arrangement through the injection tube into the wellbore. Since the components react only in a limited range, the available processing time in which the fastener must be introduced into the well increases significantly compared to a curable mass already mixed on introduction into the well, especially in series applications in which several fasteners must be set, is advantageous.
- a defined amount of a filler having a defined particle size distribution is introduced into the borehole after the introduction of the hardenable, multicomponent mass and before the fastener is screwed in mechanically, wherein the filler comprises the mixing process of the components of the hardenable mass and the mixing of the borehole still present in the borehole or cuttings in the hardenable mass additionally supported.
- the filler comprises the mixing process of the components of the hardenable mass and the mixing of the borehole still present in the borehole or cuttings in the hardenable mass additionally supported.
- the defined amount of the filler is provided to the user in corresponding packaging units.
- the filler is packaged, for example, in a small bag, a foil pouch or another container easily destructible by the fastening element.
- the defined amount of filler corresponds to 10% by volume to 30% by volume of the volume of hardenable multicomponent mass introduced into the borehole, thus advantageously mixing the curable, multicomponent mass in the borehole and optionally profiling the borehole when screwing the borehole Fastening element is guaranteed.
- the particle size of the filler preferably corresponds to 0.05 to 0.35 times the outer diameter of the fastening element, the particle size advantageously corresponding substantially to the size of the annular gap between the borehole wall and the fastening element.
- Corundum is preferably used as the filler, which has a sufficient hardness, in particular for profiling the borehole wall.
- quartz sand or other, advantageously mineral, aggregates are used as fillers, which have a sufficiently high hardness for profiling the borehole wall.
- a provided with a right-hand fastener is used, which is screwed left-handed in the hole.
- the hardenable mass is conveyed into the borehole during left-handed screwing in of the fastening element, thereby achieving a certain compression of the hardenable mass and of the borehole ground or drill cuttings in the borehole.
- a fastening element 11 here for example an M12 threaded rod with a profiling in the form of a right-hand thread, in a substrate 21, such.
- a curable, multicomponent mass 31 is in a first step with a drill 36, z. B. with a hammer drill, a borehole 22 created in the ground 21.
- the borehole depth T created is 10% greater than the required anchoring length L of the fastening element 11.
- the required anchoring length L of an M12 threaded rod in a concrete substrate is, for example, 100 mm, with which the borehole depth T is selected to correspond to 110 mm.
- the drill 36 has a nominal diameter N, which corresponds to 1.2 times the outside diameter A of the fastening element 11. With reference to the example with an M12 threaded rod, a drill 36 having a nominal diameter of 14 mm is thus selected. The drilling dust or drill cuttings 23 remaining during drilling remains in the borehole 22.
- the advantageously pasty, hardenable, multicomponent mass 31 is subsequently introduced into the borehole 22 with a discharge device, not shown here, in which drill dust or cuttings 23 are still located at least at the bottom of the borehole.
- the two components, the resin 32 and the hardener 33, of the hardenable multicomponent mass 31 are introduced into the borehole 22 unmixed.
- a defined amount of a filler 34 can be introduced into the borehole 22.
- a profiling / mixing element 12 which has a mixing section 13. Then, the fastener 11 is inserted with the mixing section 13 first in the wellbore 22 and mechanically, advantageously left-handed, screwed into the filled wellbore 22 with a rotary hammer as a rotary drive device until reaching the required anchoring length L of the fastener 11.
- a rotary drive device is in Fig. 1 only the tool holder 16 shown.
- the resin 32, the hardener 33 and part of the borehole borehole or cuttings 23 are mixed together.
- the wall of the borehole 22 is profiled by the profiling sections of the profiling / mixing element 12 to create undercuts.
- an attachment (not shown here) can be fastened to the base 21 at the free end 14 of the fastening element 11.
- the filler 34 advantageously corundum, has a sufficient hardness for profiling the wall of the borehole 22 and is made available to the user, for example in a bag.
- the defined amount of the filler 34 corresponds to 10 vol .-% to 30 vol .-% of the volume of introduced into the wellbore 22 curable, multi-component mass 31.
- the particle size of the filler 34 in this embodiment, 1 mm to 2 mm, thus at an M10 threaded rod as a fastening element 41 corresponds to 0.1 to 0.2 times the outside diameter A of the fastening element 41.
- a mixing blade is provided as a mixing section 43.
- the fastener 41 is machined into the filled borehole 22 z. B. with a screwdriver as a rotary drive device until it reaches the required anchoring length L of the fastener 41 screwed.
- the rotary drive device only the tool holder 16.
- the hardenable mass 31, the filler 34 and a part of the drill hole located in the wellbore or cuttings 23 are mixed together.
- the wall of the borehole 22 is profiled by the hard coarse filler 34 to create undercuts.
- an attachment (not shown here) can be attached to the base 21 at the free end 44 of the fastening element 41.
